What is Superhuman?
Superhuman is becoming an email agent, not an email client
Superhuman has spent the last two months turning the inbox into an agent surface: an MCP server, a Codex plugin with prebuilt skills, Draft Sync so external assistants can write into Gmail and Outlook, and now Auto Drafts that pre-write a reply to every message that needs one. The rest of the roadmap — Android calendar, multi-day iOS views, notification quick-reply — is parity work running underneath the AI push.
What is Krisp?
Krisp expands from noise cancellation into a full call-center AI stack — now with voice-fraud defense
Krisp has grown well past its noise-cancellation roots into a Call Center AI suite spanning Accent Conversion, Voice Translation (now v3), Speech Analytics, and a new Voice Security line. The recent cadence is a steady drip of biweekly web updates and monthly roundups, with real feature depth: real-time translated-call oversight, admin and audit controls, and CRM data feeding analytics scoring.

Superhuman is becoming an email agent, not an email client
◆ Current state
Superhuman has spent the last two months turning the inbox into an agent surface: an MCP server, a Codex plugin with prebuilt skills, Draft Sync so external assistants can write into Gmail and Outlook, and now Auto Drafts that pre-write a reply to every message that needs one. The rest of the roadmap — Android calendar, multi-day iOS views, notification quick-reply — is parity work running underneath the AI push.
◆ Where it's heading
The direction is to reduce the human to an editor. Auto Drafts already claims 60% of replies sent unedited and pulls context from calendar and the web, while the MCP surface lets any agent triage, draft, and schedule. Expect the mobile and calendar catch-up to continue while the AI layer absorbs more of the reply workflow.
◆ Prediction
Next likely move is wiring Auto Drafts into more tools — the changelog already promises Slack, CRM, and meeting-notes context — pushing toward send-ready replies drawn from a user's whole stack.

Krisp expands from noise cancellation into a full call-center AI stack — now with voice-fraud defense
◆ Current state
Krisp has grown well past its noise-cancellation roots into a Call Center AI suite spanning Accent Conversion, Voice Translation (now v3), Speech Analytics, and a new Voice Security line. The recent cadence is a steady drip of biweekly web updates and monthly roundups, with real feature depth: real-time translated-call oversight, admin and audit controls, and CRM data feeding analytics scoring.
◆ Where it's heading
The arc runs from cleaning up audio toward reshaping and securing it in real time for contact centers — translating and accent-converting live calls, then defending those calls against AI voice fraud. Voice Security, with deepfake detection and agent-voice verification, is the notable direction change: Krisp is now selling trust in the voice channel, not just clarity. Admin controls, audit trails, and Salesforce integration show the suite hardening for enterprise contact-center buyers.
◆ Prediction
Expect Voice Security to broaden beyond deepfake detection into more fraud vectors, and translation plus analytics to deepen their CRM ties as Krisp pushes the full suite into enterprise contact centers.
